Disclosed is a device for preparing a solution from a sample and a reagent, comprising a microfluidic array comprising a sample supply inlet (E1), a reagent supply inlet (E2), a discharge outlet (S1), a solution collection outlet (S2), a sampling zone (ZE) to which the inlets (E1, E2) are connected, first (4) and second (6) preparation chambers connected to the sampling zone (ZE), arranged to either side of the sampling zone (ZE) such that the liquid flowing from one preparation chamber to the other flows through the first sampling zone (ZE), the first preparation chamber (4) having a volume that is variable between a minimum volume and a calibrated volume. The device comprises valves interrupting the flow of the fluid at least at the two inlets (E1, E2) and the collection (S2) and discharge (S1) outlets. |
